DETAILED DESCRIPTION

For a thorough understanding of the present disclosure, numerous specific details are set forth in the following description for purposes of illustration but not of limitation, such as particularities of system structures, ports, techniques, et cetera. However, it should be appreciated by those of skill in the art that, in absence of these specific details, the present disclosure may also be carried out through other implementations. In other instances, a detailed description of well-known devices, circuits, and methods is omitted, so as to avoid unnecessary details from hindering the description of the disclosure.

The following embodiments describe toy building block robots and main control boxes for a toy building block robot according to the disclosure.

As shown in FIG. 1 and FIG. 2, a toy building block robot of an embodiment of the present disclosure comprises a main control box 10. The main control box 10 comprises a toy building-block robot main control housing, a toy building-block robot main control board 15, and a battery 13. The toy building-block robot main control board 15 is installed in the toy building-block robot main control housing. The battery 13 is connected to the toy building-block robot main control board 15, so as to supply power to the toy building-block robot main control board 15. A plurality of connection mechanisms are disposed on the toy building-block robot main control housing, which are used to engage the toy building-block robot main control housing with other components of the toy building block robot.

Particularly, the toy building-block robot main control housing comprises a bottom housing 12 and a top housing 11. An accommodation space is formed between the bottom housing 12 and the top housing 11, wherein the toy building-block robot main control board 15 is installed within the accommodation space.

For the convenience to describe the aspects of the toy building-block robot main control housing, six faces on the toy building-block robot main control housing are respectively defined as a top face 101, a bottom face 102, a front face 103, a back face 104, a left face 105, and a right face 106.

As shown in FIG. 3 and FIG. 4, the connection mechanisms of this embodiment comprise a plurality of connecting portions. The connecting portions are disposed on an outer surface of the toy building-block robot main control housing, particularly, the bottom face 102 and the back face 104 of the toy building-block robot main control housing, wherein 6 of the connecting portions are disposed on the bottom face 102, 3 of the connecting portions are disposed on the back face 104.

It can be understood that, in other embodiments, the location and the amount of the connecting portions on the main control box 10 can be changed in accordance with actual demands. The connecting portions are configured to engage into a butting slot of other components of the toy building block robot, for example, a building block, a servo, or a decoration component of the toy building block robot, thereby realizing the connection between the main control box 10 as well as the building block, the servo, the decoration component, etc.

As shown in FIG. 5 and FIG. 6, the connecting portion comprises a connection pillar 1 b 2 and a connection plate 1 b. In this embodiment, the connection pillar 1 b 2 and the connection plate 1 b are integratedly molded. Each of the connection plate 1 b is installed on the outer surface of the toy building-block robot main control housing through the connection pillar 1 b 2.

Particularly, there are various methods to fix the connecting portion on the toy building-block robot main control housing. A screw hole 1 b 1 is formed in the connection plate 1 b and the connection pillar 1 b 2, such that a screw could pass through the screw hole 1 b 1 to fix the connecting portion on the outer surface of the toy building-block robot main control housing. In other embodiments, the connecting portion and the toy building-block robot main control housing could be integratedly molded, or the connecting portion could be fixed on the toy building-block robot main control housing through adherence.

The shape of the connection plate 1 b could be various. In this embodiment, a square-shaped design is adopted. In comparison with a round shape, a square shape facilitates differentiating different aspects of the connection plate 1 b. In comparison with a rectangular shape or other shapes, since the sides of a square have a same length, the connection plate 1 b has a same structure in four aspects, and is convenient in connecting with other components of the toy building block robot.

A top face of the connection plate 1 b has direction symbols 1 b 4 disposed thereon. In the assembly process using the connecting portions, if need to assemble in accordance with a particular aspect, the direction symbols 1 b 4 could be used to determine the corresponding aspect. For instance, symbols Δ, □, ⋆, and ∘ can be disposed on the connection plate 1 b, so as to respectively represented four aspects of the connection plate 1 b. In addition, other symbols, graphs, or characters could be adopted to represent the aspects of the connection plate 11. For instance, the characters E, W, N, and S are used to represent four aspects of the connection plate 1 b.

The connection pillar 1 b 2 has at least one set of limit grooves 1 b 3 which is disposed opposite to each other. The limit grooves 1 b 3 are used to match limit protrudes on a butting slot of other components of the toy building block robot, thereby limiting the connecting portion within the butting slot. In this embodiment, four limit grooves 1 b 3 are uniformly distributed on the connection pillar 1 b 2. Each of the limit grooves 1 b 3 is disposed in alignment with the center of each side of the square connection plate 1 b, and two opposite limit grooves 40 are disposed on a same diameter of the cylindrical connection pillar 1 b 2.

A chamfer 1 b 5 is disposed on a junction between the connection pillar 1 b 2 and the connection plate 1 b. The chamfer 1 b 5 matches a chamfer on the butting slot of other components of the toy building block robot, which facilitates the connection between the connecting portion and other components.
